CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application Serial No. 10-2017-0089100, filed on Jul. 13, 2017, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference.

BACKGROUND 1. Field

The disclosure relates, generally, to an electronic device and a method for displaying information, and more particularly, to an electronic device and a method for displaying information based on user authentication.

2. Description of the Related Art

As information communication and semiconductor technologies are developed, electronic devices have become multimedia devices providing various services, such as broadcast services, wireless Internet services, camera services, and electronic payment services.

When a user purchases an article in a shop, the user may pay for the article by using an electronic card that is registered in the electronic device, instead of a real card (e.g., a credit card) through the electronic payment service.

The user may execute a bookmark function for favorite cards on a locked screen of the electronic device to display electronic cards on the locked screen. In this case, information provided may be limited by the electronic device in a locking mode.

When the electronic device is in the locking mode, the user may need to release the locking mode to receive desired information from the electronic device. Although the electronic device may provide some information in the locking mode, the information provided by the electronic device is significantly limited and personal information may be limited from exposure. Whenever the locking mode needs to be released, the electronic device requires user authentication. Thus, the experience of the user using the electronic device may be interrupted, so the user may experience inconvenience.

The processor 120 may include a main processor 121 (e.g., a central processing unit or an application processor) and an co-processor 123 (e.g., a graphic processing device, an image signal processor, a sensor hub processor, or a communication processor (CP)), which operates independently from the main processor 121, additionally or alternatively uses less power than the main processor 121, or is specified to a designated function. In this case, the co-processor 123 may operate separately from the main processor 121 or embedded.

The co-processor 123 may control at least some of functions or states associated with at least one component (e.g., the display device 160, the sensor module 176, or the communication module 190) among the components of the electronic device 101 instead of the main processor 121 while the main processor 121 is in an inactive (e.g., sleep) state or together with the main processor 121 while the main processor 121 is in an active (e.g., an application execution) state. The co-processor 123 (e.g., the image signal processor or the CP) may be implemented as a part of another component (e.g., the camera module 180 or the communication module 190) that is functionally related to the co-processor 123. The memory 130 may store a variety of data used by at least one component (e.g., the processor 120 or the sensor module 176) of the electronic device 101, for example, software (e.g., the program 140) and input data or output data with respect to commands associated with the software. The memory 130 may include the volatile memory 132 or the nonvolatile memory 134.

The program 140 may be stored in the memory 130 as software and may include an operating system 142, a middleware 144, or an application 146.

The input device 150 may be a device for receiving a command or data, which is used for a component (e.g., the processor 120) of the electronic device 101, from an outside (e.g., a user) of the electronic device 101 and may include, for example, a microphone, a mouse, a keyboard, a touch panel (or a touch circuit), a pressure sensor, or the like.

The sound output device 155 may be a device for outputting a sound signal to the outside of the electronic device 101 and may include a speaker used for general purposes, such as multimedia play or recordings play, and a receiver used only for receiving calls. The receiver and the speaker may be either integrally or separately implemented.

The display device 160 may be a device for visually presenting information to the user and may include a display, a hologram device, or a projector and a control circuit for controlling a corresponding device. The display device 160 and a touch panel, which is the input device 150, may be stacked to configure the touch screen.

The audio module 170 may convert a sound and an electrical signal in dual directions. The audio module 170 may obtain the sound through the input device 150 or may output the sound through an external electronic device (e.g., the electronic device 102, a speaker, a headphone, etc.) wired or wirelessly connected to the sound output device 155 or the electronic device 101.

The sensor module 176 may generate an electrical signal or a data value corresponding to an operating state (e.g., power or temperature) inside or an environmental state outside the electronic device 101. The sensor module 176 may include a gesture sensor, a gyro sensor, a barometric pressure sensor, a magnetic sensor, an acceleration sensor, a grip sensor, a proximity sensor, a color sensor, an infrared sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The interface 177 may support a designated protocol wired or wirelessly connected to the external electronic device 102. The interface 177 may include, for example, a high-definition multimedia interface (HDMI), a universal serial bus (USB) interface, an SD card interface, or an audio interface.

A connection terminal 178 may include a connector that physically connects the electronic device 101 to the external electronic device 102 an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).

The haptic module 179 may convert an electrical signal to a mechanical stimulation (e.g., vibration or movement) or an electrical stimulation perceived by the user through tactile or kinesthetic sensations. The haptic module 179 may include, for example, a motor, a piezoelectric element, or an electric stimulator.

The camera module 180 may shoot a still image or a video image. The camera module 180 may include at least one lens, an imaging sensor, an image signal processor, or a flash.

The power management module 188 may be a module for managing power supplied to the electronic device 101 and may serve as at least a part of a power management integrated circuit (PMIC).

The battery 189 may be a device for supplying power to at least one component of the electronic device 101 and may include a non-rechargeable (primary) battery, a rechargeable (secondary) battery, or a fuel cell.

The communication module 190 may establish a wired or wireless communication channel between the electronic device 101 and the external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and support communication execution through the established communication channel. The communication module 190 may include at least one communication processor operating independently from the processor 120 (e.g., the AP) and supporting the wired communication or the wireless communication. The communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., an local area network (LAN) communication module or a power line communication module) and may communicate with the external electronic device using a corresponding communication module among them through the first network 198 (e.g., the short-range communication network such as a Bluetooth, a WiFi direct, or an Infrared Data Association (IrDA) standard network) or the second network 199 (e.g., the long-distance wireless communication network such as a cellular network, an internet, or a computer network (e.g., LAN or WAN)). The above-mentioned various communication modules 190 may be implemented into one chip or into separate chips, respectively.

The wireless communication module 192 may identify and authenticate the electronic device 101 using user information stored in the subscriber identification module 196 in the communication network.

The antenna module 197 may include one or more antennas to transmit or receive the signal to or from an external source. The communication module 190 (e.g., the wireless communication module 192) may transmit or receive the signal to or from the external electronic device through the antenna suitable for the communication method.

Some components among the components may be connected to each other through a communication method (e.g., a bus, a general purpose input/output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)) used between peripheral devices to exchange signals (e.g., a command or data) with each other. The command or data may be transmitted or received between the electronic device 101 and the external electronic device 104 through the server 108 connected to the second network 199. Each of the electronic devices 102 and 104 may be the same or different types as or from the electronic device 101. All or some of the operations performed by the electronic device 101 may be performed by another electronic device or a plurality of external electronic devices. When the electronic device 101 performs some functions or services automatically or by request, the electronic device 101 may request the external electronic device to perform at least some of the functions related to the functions or services, in addition to or instead of performing the functions or services by itself. The external electronic device receiving the request may carry out the requested function or the additional function and transmit the result to the electronic device 101. The electronic device 101 may provide the requested functions or services based on the received result as is or after additionally processing the received result. To this end, a cloud computing, distributed computing, or client-server computing technology may be used.

FIGS. 2A and 2B are diagrams of procedures of releasing a locking mode of an electronic device, according to an embodiment. FIG. 2A is a view conceptually illustrating a conventional procedure of releasing a locking mode, and FIG. 2B is a view conceptually illustrating a procedure of releasing a locking mode.

In the case of the conventional procedure of releasing the locking mode, the access to an unlocked screen 202 is interrupted by a locked screen (locking mode screen) 201 as illustrated in reference sign (a-1) of FIG. 2A. Until the locking mode is released, the electronic device 101 may prevent the personal information of the user from being exposed.

Thereafter, when user authentication passes through a pattern input, the input of a PIN password, or fingerprint recognition, the electronic device 101 releases the locking mode and exposes the unlocked screen 202 including the personal information as illustrated in reference sign (a-2) of FIG. 2A.

When the exposure of the personal information is limited due to the locking mode of the electronic device 101, although a security level may be raised, a user may feel that the experience is interrupted. Since the personal information is recognized only when the locking mode is released, the rapid access to the personal information is limited and the user may feel a barrier to locking mode.

As illustrated in FIG. 2B, the concept of partial unlocking is applied to provide the continuous user experience until the personal information is recognized.

As shown in (b-1) of FIG. 2B, the electronic device 101 may apply the concept of a partial unlocked screen 203 between the locked screen 201 and the unlocked screen 202, in the locking mode. The partial releasing of the locking mode may be performed through a partial authentication scheme. The partial authentication scheme may refer to an authentication scheme of automatically partially releasing the locking mode in the situation that the user has no intent to release the locking mode of the electronic device 101. Alternatively, the partial authentication scheme may refer to an authentication scheme of partially releasing the locking mode in advance before receiving an intentional user input for releasing the locking mode of the electronic device 101.

The partial authentication scheme may employ information captured using an image sensor to automatically perform user authentication regardless of the intent of the user. While the user is facing the locked screen 201, the electronic device 101 may acquire bio-information of the user, such as the face information or iris information, by using the image sensor. When the partial authentication passes based on the acquired bio-information, the electronic device 101 may display the partial unlocked screen 203 including first-level information as the locking mode is partially released as shown in reference sign (b-2) of FIG. 2B. The partial authentication scheme may be called a non-contact user authentication scheme in that authentication is performed through a non-touch user input.

When the full authentication passes to fully release the locking mode in the state that the first-level information is displayed, the electronic device 101 may provide the unlocked screen 202 including second-level information having a security level higher than a security level of the first-level information as the locking mode is fully released. A user input for fully releasing the locking mode may include user inputs such as a pattern drawn for releasing the locking mode, a password input (e.g., a number or a character), fingerprint touch input for fingerprint authentication, etc. A user authentication scheme of fully releasing the locking mode may be referred to as a full authentication scheme. In addition, when a user contact is required to fully release the locking mode, the user authentication scheme may be referred to as a contact-based user authentication scheme.

In addition, the second-level information having a security level higher than the security level of the first-level information may include a larger amount of information, additional personal information, additional detailed information, or information requiring stronger access authority, as compared with the first-level information, or may include at least a portion of the first-level information.

Meanwhile, to fully release the locking mode, a user may use a partial authentication scheme as well as a full authentication scheme. For example, the locking mode may be released through iris recognition or face recognition.

FIGS. 3A-3I are diagrams of execution screens of a payment application as the locking mode is partially released, according to an embodiment.

First, in FIG. 3A, the electronic device 101 may provide a locking mode screen 301 as the electronic device 101 is in a locking mode. The locking mode screen 301 may include a user interface for receiving a pattern or a password for unlocking. In the locking mode, the user may make a user input of swiping toward a display from a bezel area provided at a lower end of the electronic device 101 to execute a bookmark function for favorite cards of the payment application.

The electronic device 101 may gradually show one electronic card 302 of cards, which are previously registered in the electronic device 101, from the lower end of the electronic device 101 while displaying the electronic card 302 on a screen, by executing a payment application (e.g., Samsung Pay™) based on the user input in FIG. 3B and FIG. 3C.

The electronic card 302 may include a card for payment, a card for banking, a membership card, and a card for managing personal information. For example, the card for payment may include at least one of a credit card, a bearer prepaid card (e.g., a gift card), a check card, and a debit card.

The electronic device 101 may perform partial authentication. The electronic device 101 may perform the partial authentication when receiving the user input (e.g., a swipe input). In addition, when the locking mode screen 301 is displayed and a predetermined period of time (e.g., one second to three seconds) elapses, the partial authentication may be performed. Further, in FIG. 3B, the electronic device 101 may perform the partial authentication during the state of a transition effect that the electronic card 302 gradually appears or may perform the partial authentication in a standby state of receiving a user input as the electronic card 302 is displayed.

The partial authentication may be performed in background based on bio-information (e.g., face information or iris information) acquired through the image sensor.

Meanwhile, when the partial authentication is in progress or is finished, the electronic device 101 may display visual information such as an indicator (or a cue) 303 in FIG. 3C, on the display. The indicator 303 may include an icon having the shape of an eye to represent that iris recognition is in progress or finished for full authentication, or an icon having the shape of a face to represent that the face recognition is in progress or finished for full authentication.

When the partial authentication passes, in FIG. 3D, the electronic device 101 may display first-level information 311 on the display as the electronic device 101 is partially released from the locking mode. The first-level information 311, which is information on a level which does not require a higher security level, may include at least one of a spend amount this month or last month and a budget for a card. The electronic device 101 may display the first-level information 311 on the execution screen of the first payment application (e.g., Samsung Pay™).

In FIG. 3E, an additional first-level information 312 may be displayed on the display, based on the user input (e.g., a flip or swipe gesture) on the display made in FIG. 3D. The additional first-level information 312 may include lower-level personal information such as a spend amount of a card, an amount to be paid, a budget for the card, and a card benefit to a cardholder. Accordingly, a user may rapidly and clearly recognize the card usage status of himself/herself before making payment, to manage expenses in a smart manner.

Meanwhile, in FIG. 3E, a screen may include a user interface 313 for accessing second-level information having a security level higher than a security level of the first-level information. In FIG. 3F, the electronic device 101 may provide a locking mode screen, which includes a UI 314 for user authentication performed in a touch scheme (e.g., a scheme of inputting a pattern), based on a user input for selecting the UI 313.

In FIG. 3F, when a user input for unlocking is received through the UI 314, the electronic device 101 may perform full authentication based on the received user input. When the full authentication passes, the electronic device 101 may fully release the locking mode and may display second-level information 321 having a security level higher than a security level of the first-level information on the display in FIG. 3G. The second-level information 321 may include, for example, a spend amount of a card, a budget of a card, spend amount for each card, budget for each card, and a spending analysis graph.

The electronic device 101 may display the second-level information 321 on the execution screen of a second application (e.g., Samsung Planner™). The first application to display the first-level information may be identical to the second application to display the second level-information or the first and second applications may be different from each other. The first-level information may be information included in a screen displayed as an execution result of a first function of a specific application. In addition, the second-level information 321 may be information included in a screen displayed as the execution result of the second function of the specific application.

In addition, the electronic device 101 may automatically perform the partial authentication when a specific period (e.g., one second to three seconds) elapses after the locking mode screen 501 is displayed.

When the user authentication passes as iris recognition or face recognition is performed for partial authentication, the electronic device 101 may partially release the locking mode.

When the locking mode is partially released, the electronic device 101 may display first-level information 511 on the display as in FIG. 5C. The first-level information 511 may be information having a security level higher than a security level of the third-level information 502 displayed on the locking mode screen 501. The first-level information 511 may include a larger amount of information, more personal information, more detailed information, or information requiring stronger access authority, as compared with the third-level information, or may include at least a portion of the third-level information 502.

In FIGS. 5A-5C, the first-level information 511 may include, for example, information provided by a messenger application. The first-level information 511 may include detailed information associated with notification information 502-1 included in the third-level information 502. The detailed information may include at least a portion of a body of a message or information on a transmission time of the message.

Meanwhile, when the user makes a user input for fully releasing the locking mode, the electronic device 101 may display second-level information provided by the messenger application when the user authentication passes based on the user input. The second-level information may include an attached file of a message, a carbon copy of the message, another message, a sender of the message, or a full body of the message.

As described above, the locking mode may be automatically partially released without an additional user input for performing unlocking and thus a user may rapidly recognize the content of a message. The content of the message is hidden when another person uses the electronic device 101 and is displayed when the user uses the electronic device 101. Accordingly, the security of the electronic device 101 may be improved.
